System.Xml 2.0.0.0 4.0.0.0 System.Object The class is an XSLT processor that supports the XSLT 1.0 syntax. It is a new implementation and includes performance gains when compared to the obsolete class. The structure of the class is very similar to the class. The method loads and compiles the style sheet, while the method executes the XSLT transform. Support for the XSLT document() function and embedded script blocks are disabled by default. These features can be enabled by creating an object and passing it to the method. For more information, see Using the XsltCompiledTransform Class and Migrating From the XslTransform Class.

Security Considerations

When creating an application that uses the class, you should be aware of the following items and their implications: XSLT scripting is disabled by default. XSLT scripting should be enabled only if you require script support and you are working in a fully trusted environment. The XSLT document() function is disabled by default. If you enable the document() function, restrict the resources that can be accessed by passing an object to the method. Extension objects are enabled by default. If an object containing extension objects is passed to the method, they are utilized. XSLT style sheets can include references to other files and embedded script blocks. A malicious user can exploit this by supplying you with data or style sheets that when executed can cause your system to process until the computer runs low on resources. XSLT applications that run in a mixed trust environment can result in style sheet spoofing. For example, a malicious user can load an object with a harmful style sheet and hand it off to another user who subsequently calls the method and executes the transformation. These security issues can be mitigated by not enabling scripting or the document() function unless the style sheet comes from a trusted source, and by not accepting objects, XSLT style sheets, or XML source data from an untrusted source.

Constructor 2.0.0.0 4.0.0.0 The following conditions must be met in order to step into the code and debug the style sheet: The parameter is set to true. The style sheet is passed to the method either as a URI, or an implementation of the class that implements the interface. The interface is implemented on all text-parsing objects. In other words, if the style sheet is loaded using an object, such as an or , or an implementation that does not implement the interface, you cannot debug the style sheet.
